Description

one

The invention relates to the field of metal forming and can be used in those intended for the brand of rolled steel, pipe and so on.

A striking machine of a stamping machine is known, containing two parallel shafts, one of which carries hammers, as well as a mechanism for coaxing them to the starting position, which is knocked out in the form of linked levers, and the other, which is rotated from pyvmotsilipdra through a gear-rack and pinion transmission, the cams are rigidly fixed in contact with the above hammers and during the working stroke of the pneumatic cylinder. A disadvantage of the known device is the need for an additional drive for cocking hammers. This makes it difficult to reconcile the drive of the percussion mechanism and the arcing lead and requires a complex control scheme.

The described device differs from the well-known fact that the hammer cocking mechanism is made in the form of a finger, which is freely mounted on the same shaft as the hammer, and is made of a gear with bristles, which is rigidly fixed to the gear shaft on the drive shaft opposite to the rack and pinion gear, and a protrusion, which fits with a finger, mounted on a lever nearby from it, while the cocking levers of the hammers are spring-loaded.

On the fit. 1 shows the proposed device, a plan view; in fig. 2 - section but

A-A .na f, ig. one; in fig. 3-section on BB Iia

FIG. one; in fig. 4 - section but bb in f.ig. one.

The device consists of two parallel

shaft / and 2, placed in the supports 3. On the shaft

/ dressed with the possibility of turning the hammer 4.

Levers 5 and 6 are fixed on the same shaft, connected by a bar 7, which is passing hammers passing by the node. On the shaft 2, the gears 8 and 9 and the cams 10 are rigidly mounted. The gear 8 is connected through the rack rail //

pneumocycle and core of 12 springs of the percussion mechanism, and shchestren 9 is in engagement with free squeegee on the shaft 1 of the scooper 13, which is squeezed tightly with the finger 14. When the hammer 14 is cocked, it comes in contact with the hammer 15, which is coiled on the lever 6. Levers 5 I 6 with a strap 7 springs 16. Can be lowered onto the stops / 7. In the cocked position, the hammers rest on the bar 18. Hammers 4: when working, panos t hit the stamps 19.

The device works as follows. In the cocked position, the finger 14 is at the top and, pressing the protrusion 15, holds the levers 5 1 6 with the bar 7 in the upper

position Nlanka 7 forces all hammers

4 to be propped up and lean on the bar 18. The rake is / - / zi.imaet left (in Fig. 2) extreme position. There is a certain angle f between the contacting surface .1, and the hammer 4. And “ulach.ka 10 and. (Fig. 3). When feeding a masonry blow, the pneumatic cylinder 12 forces the rail AND to move to the right. Gear rake

8runs the shaft 2 with the cam M. I 10 n gear

9iHo Hour hand. Gear1g 9 rotates counterclockwise gear //; and a finger 14, which, tempering the protrusion 15. allows the springs / 5 01 to release the lever 5 n 5 with the bar 7 on the rails 17. The gear ratio between gears 9 and 13 is chosen such that the lowering of the levers on the stops occurs during shaft rotation 2 at an angle f. Thanks to this, the cams 10 come into contact with the hammers 4 already after lowering the bar 7 to the lower position, which ensures the free lowering of the hammers on the branding 19. After the levers 5 and 6 are stopped in the lower position, the contact of the finger 14 with the protrusion is broken 15. Finger v. M: Eat with gear 13 continues to turn freely until the shaft 2 stops. Shaft 2 stops at the end of the stroke when the piston of the cylinder J2 takes the rightmost position. A command is then issued to reverse the cylinder. When reversing the .sinder 12, the shaft 2 begins to rotate anti-clockwise, 3 clockwise, the cams return

10 in the original position. Shestern 9. rotates a. Place with the shaft. Pokes the finger 14,

with which, reaching the protrusion 15, begins to dry it. together with the levers 5 and 6. and the bar 7. Placement 7. on the other hand, catch the hammers 4, and cock them. A1ekhanizm.iz again takes its original position.

Subject invention

The impactor is a glue-strung ma "1Is" containing two parallel shafts, one of which is the displacement impacting the hammer butts, as well as the mechanism for cocking them into one similar position, made in the form of levers attached to the strap. the other, rotated from the wind cylinder through the rack-and-pinion gear, cams are rigidly fastened, contacting with the above-mentioned hammers during the operation of the pneumocylinder, characterized by the fact that, in order to simplify the design of the platen mash, due to the disconnection of the drive, the valve is rotated. my Trays and Ensuring accurate synchronization of the device, the hammer cocking mechanism is made in the form of a finger freely mounted on the same shaft with hammers, made completely with a gear, meshed with a gear wheel fixed in the device firmly fixed on the drive shaft, and interacting with his finger of the protrusion, s.mont, irovashyugo on the closest to its lever, etc., etc., and it is. The levers of the cocking of hammers are spring-loaded.
